of the system.

WARNING: To adequately display the software application, it is

important to maintain a minimum screen resolution of
1024x768 with 96 dpi.

™

System. Use of unauthorized software,

WARNING: Some of the equipment on the NetGuard Network must

utilize the hospital emergency power system. Failure to do
so will result in loss of monitoring during extended periods
of power failure. The back-up power time period for the
NetGuard Network is limited.

WARNING: Changes to the NetGuard server configuration and client PC

software should not be performed without the guidance of
a qualified service representative.

WARNING: Do not use the NetGuard device in an explosive atmosphere

or in the presence of flammable anesthetics or gases.

Cautions

CAUTION: For proper operation use with UL agency approved ethernet

cables.

CAUTION: For proper operation, do not use the equipment with a

frayed or damaged power cord or ethernet cable.

CAUTION: Do not use a damaged or broken unit or accessory.

CAUTION: For proper operation never place fluids on top of the server.

In case of accidental spillage, remove power, wipe clean
immediately and have the system serviced to ensure no
hazard exists.

CAUTION: The server and client PC for this device must only be setup

by qualified service personnel.

CAUTION: Do not block the client PC’s speakers. Set the volume levels

to ensure that alarms can always be heard.

CAUTION: Speaker volume should be set high enough to hear an

alarm above ambient noises.

Instrument Description

1.1 Introduction

This section of the service manual provides an overview of the NetGuard System, followed
by more detailed information.

1.2 Overview

The NetGuard System is an ambulatory monitoring system that issues alerts automatically to
clinicians when it recognizes potentially life-threatening cardiac rhythms in monitored
patients. The system monitors patient ECG and heart rate and issues alerts whenever specific
arrhythmias are detected or the measured values deviate from acceptable ranges.

The NetGuard System (shown in FIGURE 1-1) consists of the NetGuard devices, a wireless
infrastructure, a central server, one or more client PCs, and proprietary software running on
the server and client PCs.

The server application collects patient data from the reusable device via ceiling or wall
mounted access points. This allows patients to move within the designated areas of the
hospital. The NetGuard wireless network is based on ZigBee protocol (802.15.4) which
operates in the 2.4 GHz band.

Instrument Description Core Functions

1.3 Core Functions

The NetGuard client application displays, records, and recalls patient ECG data (i.e., heart
rate, and waveforms). At installation of the system, the following items are setup:

• User Management

• Room Management

• Monitor Group Management

• Alarm Management

• Database Management

• Network / Device Management

In the event of a Lethal System level alarm, a hospital staff member must see the patient to
silence the alarm. All other alarms, such as System level heart rate alarms and Technical
alarms can be silenced at the NetGuard client application.

1.4 Connectivity

The reusable device is powered when connected to the disposable electrode. Cardiac
signals and device status are transmitted wirelessly to access points. The access points are
connected via Ethernet cabling to the network switch, and a server. Patient data is processed,
and sent to the NetGuard client application.

System Modules and Components Instrument Description

1.6 System Modules and Components

1.6.1 Patient Worn Device

The patient worn device consists of two components: a disposable electrode and reusable
transmitter. The disposable consists of a lead wire set, a coin cell battery, and a receptacle
for the reusable. The reusable analyzes the ECG data from the disposable and transmits it
wirelessly to the access points.

1.6.2 Access Points

Access points route data between the patient worn device and the server. The reception
range of the access point is dependent on the surrounding environment (e.g., wall
construction, etc.) and is determined during the site survey.

1.6.3 NetGuard Access Point Switch

The switch connects and powers (PoE) the access points to the NetGuard server and the
hospital network.

1.6.4 NetGuard Server Application

The server application receives data from the patient worn devices and stores it in the patient
database. This application also distributes the data from the database to the client
application.

1.6.5 NetGuard Client Application

The client application runs on designated PCs and supports the following:

• Patient admission and discharge from the system

• Displays alarms and patient heart rate data

• Prints reports and other patient related information

Repair Information

2.1 Introduction

This section provides the necessary technical information to perform repairs to the NetGuard
System. The most important prerequisites for effective troubleshooting are a thorough
understanding of the system functions. If necessary, refer to the NetGuard Operating
Instructions (P/N 0070-00-0678-XX), which describes instrument functions and features in full
detail.

2.1.1 Safety Precautions

If any of the instrument covers are removed, make certain to observe the proper anti-static
precautions.

2.1.2 Equipment and Special Tools Required

When performing system repairs, the following special tools may be needed:

• Laptop Computer

• Test Device Setup

• Bootstrap Loader

• CAT5E Cable Tester

• PoE Tester

• Wi-Fi Packet Analyzer

NetGuard Service Manual 0070-10-0685 2 - 1

Troubleshooting Repair Information

Since no repairs are performed to the access points or reusables, other than reprogramming,
the previously listed tools can determine the location of the faulty components.

Only trained personnel are responsible for the service of equipment purchased from Mindray
DS USA, Inc. If opening the server is necessary, power it down and vacuum any
accumulated dust around the fan blades before opening it.

NOTE: The hospital is responsible for maintaining their network

components.

2.2 Troubleshooting

Separate the NetGuard components into the following sections:

1. Patient worn devices

2. Access Points

3. Network Rack Components

4. Client PC(s)

During the NetGuard installation process, an NetGuard Installation Verification Document
was completed listing all the MAC addresses, IP addresses, Subnet Mask addresses assigned
to the access points, server, and client PC(s). Always have a copy available for reference. If
a copy is not available, contact a service representative or authorized distributor that
installed the system.

Prior to troubleshooting a network problem, verify the following areas:

• Review Site Survey documentation

• All AC and DC power connections are secure.

• All Ethernet cable connections are secure. Verify connection and communication LEDs on
the switch. Affected cable runs could be tested with a cable tester for continuity.

• IP addresses for the server and client application

• Equipment assignment for the patient devices at the NetGuard client application

• Refer to diagram in the NetGuard Customer Installation Guide (P/N 0070-00-0686) for
LED status.

• View server or PC logs
